R'OTARY FILING-MACHINE.

. SPECIFICATION forming part of Letters Patent No. 279,108, dated June5, 1883.'

Application filed Felnuary 5, 1883. (No model.) t I 7'1) mi! whom it mayconcern Be it known that-I, DE Loss H. Srnrnmvs, of Riverton, in thecounty of Litchfield and State of Connecticut,- l'iaveinvented a new andlmproved Rotary Filing-lVIaehine, of which the following is afull,clear, and exact description.

The object of the invention is to make a uniformly smooth surface onmetallic rules or similar articles, as hereinafter described.

Reference is to be had to the accompanying drawings, formingpart of thisspecification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of my improved Fig. 2 is a plan view of thesame; and Fig. 3 is a face view of the wheel, show ing the position ofthe slide or carriage.

Upon a suitable stand or table, A, is a horizontal shaft, a, sustainedin pillow-blocks b, and carrying at one end a circular disk or wheel, B,which is formed upon its face and near its edge with a roughened surfaceof suitable character. A standard, 0, on bed A carries at its upper enda horizontal slideway, d, and upon this slideway a slide or carriage, D,is sustained. This construction gives a long and solid'bearing to thecarriage, so that vibration is prevented. At its end next the wheel thecarriage is provided with a frame, E, formed to inclose the upper partof the wheel, and at the side next to the front face of the wheel theframe is formed with a vertical flange for carrying the rule against thewheel. The carriage is fitted for endwise movement by means of atreadle, f, and levers g. The wheel B is to be revolved at moderatespeed by power applied to its shaft in any suitable manner. The rulesare placed upon the carriage in different positions, according towhether they are to be reduced their entire length or for filing onlythesurface of the joint.

In Figs. l and 3 a rule, 1', is shown as placed in position for reducingthe surface the whole length, and in Fig. 2 a half-rule is shown asplaced for filing the side of the main joint. The part c of the carriagehas at the bottom arib on which the rule is supported, and at the end astop, which prevents the rule from beingcar ried off the bed. The workbeing put in position, the operator moves the carriage back by pressingupon the treadlef, thus carrying the rule against the wheel.

It will be observed that the supports of the carriage are behind thewheel, while the frame on which the rule is placed is in front of thewheel. This enables the operator to stand closely by the machine whileoperating the treadle.

The location of the slide and frame being at the outer edge of thewheel, the joint to'be filed is carried against the wheel, where the cutwill be made in lines nearly parallel with the sides of the rule,thereby making nearly straight .work on the surface of the joint.

The carriage and frame may be placed either horizontally or vertically.I do not limit myself in that respect, nor to the other details ofconstruction exactly as described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-.

In a rotary filing-machine, the combination,

with the filing-wheel B and the sliding can riage D, of a frame, E,attached to the car- -riage, inclosing the wheel, and provided with avertical flange, 0, said flange being constructed to support the rule,substantially as described.
